  3. 乘客損失的時間

乘客損失時間是指乘客因班次缺少和延誤而損失的時數。

它說明損失了多少小時、這些時間流失到哪裡，以及由誰承擔。沒有人會計算每個班次上的乘客人數，因此乘客數是以模型推估的，每項數字都附有範圍。

  1. Bus times已測量
  2. Riders per trip預估
  3. Hours lost, by causeExplained
  4. Total, with range預估
When the buses came is measured. How many riders were on them is modelled. The range comes from the modelled part.

What is measured, estimated and explained

已測量

When each bus reached each stop, from live positions, compared with the timetable.

預估

How many riders were on each trip, and so the hours lost and the dollars. These carry a range.

Explained

How the pieces fit together. This page says it in words; it does not publish settings.

我們如何計算

  1. We find the trips that did not come, ran late or ran slow. This uses where each bus actually was, as the On time page explains.
  2. We estimate the riders on each trip. We take the route’s published boardings for the day type and spread them across the day, then divide by the trips scheduled.
  3. For each problem we work out the time a typical rider lost. The five kinds are listed below.
  4. We add the hours up. A trip is counted once: a cancelled trip is not also counted as a missed transfer.
  5. We share each trip’s hours across the places it passes through, and print a range beside the total. The route total is firmer than any one ward.

時間花在哪裡

  1. 等候一直沒有來的公車The riders who would have taken the trip, times the wait for the next bus that did come.
  2. 等候誤點的巴士Riders on trips more than 5 minutes after the timetable, times how late they ran, weighted for how busy the route is.
  3. 錯過轉乘When a trip runs later than a short connection allowance, some riders miss their connection and wait for the next one.
  4. 緩慢班次Running time beyond the timetable. A rider is on board for part of it, on average.
  5. 列車行駛緩慢The same idea for the O-Train.

每個行程的乘客人數是以模型估算

Nobody counts riders on each trip. The model starts from a route’s published boardings for a day type. It spreads them over the day using a published or network profile, and divides by the trips scheduled in each hour. The page names the model, its sources and its limits next to every figure.

Worked example

Illustrative example, rounded

Route 7, one weekday morning, one direction. These numbers are made up to show the steps, then rounded. They are not from a real day, and other routes will not look like this.

#CauseWhat we worked with損失的時數
1One trip did not comeAbout 40 riders waited about 10 minutes for the next bus7 h
2Three trips ran lateRiders on those trips, weighted for how busy the route is3 h
3A late trip, missed transfersA few riders missed their connection1 h
4The route ran a little slowExtra time on board2 h
總計range about 10 to 16About 13 h

The causes are worked the same way, each with its own allowances. The example shows the shape of the sum, not the settings.

我們有多大把握

Every figure is an estimate with a range printed next to it. The range is wider when the model has less to go on, and a trip it has no figure for is left out, counted and lowers our confidence. It is never counted as no loss.

We will publish test results once a real back-test exists.

限制

  • It is an average. A full peak trip and an empty trip share a number.
  • Direction is split by the timetable unless the operator publishes it.
  • Where a route has no hourly profile of its own, the network’s is used.
  • Riders who gave up on the bus are not counted.
  • By place: a trip’s hours are shared across the places of its timepoints. Any one ward is approximate. Stops with no known ward are shown as “Not placed”.
  • Dollars appear only when a published value of time is supplied, with its source.

What would change the number

  • More trips judged, or a fix to how a trip was judged.
  • New published boardings, or a better hourly profile.
  • A change to the method. Each change is dated on this page and past months keep the method they were worked out with.

Check a number

Anyone can send us a case. City staff and councillors’ offices are answered first. We run it ourselves, from the raw record, and send back the figure and the working in words.

What to include

  • The route or ward
  • The date or month
  • The figure you saw, with a link or a screenshot
  • What you expected, and why (optional)
Send the case

It goes to us through the contact form.

接下來會怎樣

We run the case ourselves and reply with our figure and the steps in words. If we find an error, it goes on the corrections page. We do not send the formula or its settings, so a figure cannot be tuned for or against.
